One of the best ways to discover the beauty of Cusco is to explore the city by foot. Not only will you get the lay of the land this way, but you will also uncover so many hidden gems! When you start your voyage, expect to find lots of narrow cobblestone streets, charming side shops and art galleries, and, of course, roaming llamas.
You will also come across locals dressed in traditional clothing. Although many residents dress in this kind of attire in their everyday lives, others do so to make money. They will happily welcome photo opportunities, just as long as you tip them afterward. While it is completely acceptable to take photos of or with these hard-working people — with their consent — make sure not to leave them empty-handed as these photo shoots are their job.
